Unicode display engine.

No joy "over here" on Linux.
Arial Unicode MS.
My "problem" (well, apart from all the other ones . . . ) is HOW to get
my Devawriter Pro
to "do" 'standard' (lots of quotation marks floating around, sorry)
Hindi halant entry rather
than the non-standard method (which works cross-platform, but doesn't
port well to fonts other than my own),
and this depends on the Zero Width Joiner being enabled to strut its
funky stuff regardless of where it is.
Personally, as the Indians (see below) go their own sweet way, I have no
particular problem going my sweet
way (in case you haven't worked that one out already), but, rather like
passing exams, degree certificates
and all those things which I don't like much (but have by the bucket
load), I realise that the world would be even more
disordered than it is without standards.
AND there are voices pushing for me to sort this halant thingy out. AND,
if one wants to be crude, I'm banging my head
up against ADOBE; and like David I really would rather like to come
galumphing back with Goliath's head.
Digging around on the internet I find that the Indians, apart from
having a time-zone that differs from their neighbours
by 30 minutes instead of an hour, also "type different" as they really
cannot be bothered that much about interoperability
(even though the Indian government has signed the Unicode
something-or-other) and carry on rather like Bulgarians did in 1996;
the difference being that Bulgarians being creatures of fashion, they
jumped on the Unicode train as soon as it showed up.
The Indians keep using their non-standard font systems; a sort of
reflection of Hinduism - extremely tolerant, and extremely chaotic;
probably rather jolly in religious terms, but not in the world of computers.
